antennae
Definition
Antennae are paired, elongated sensory organs that are found on the heads of insects and other arthropods. They are used for sensing the environment, including detecting movement, smell, and taste.
Antennae are made up of many segments, and they are covered in tiny hairs. The hairs are sensitive to vibrations, and they help insects to sense their surroundings.
In addition to sensing the environment, antennae are also used for communication. Insects use antennae to send and receive signals to each other, and they can use these signals to identify each other, attract mates, and warn of danger.
The shape and size of antennae can vary depending on the species of insect. For example, the antennae of butterflies are often long and thin, while the antennae of beetles are often short and stubby.
Antennae are an important part of the sensory system of insects, and they help insects to survive and reproduce.

AQA Science Exam Question and Answer
Question:
What is the primary function of antennae in insects, and how do they contribute to the insect's ability to perceive and interact with their environment?
Answer:
- The primary function of antennae in insects is to serve as sensory structures. They are equipped with specialised sensory cells and receptors that allow insects to detect and interpret various environmental cues. These cues include chemical signals (pheromones) released by other insects, changes in temperature and humidity, and even air movements. By utilising their antennae, insects can gather vital information about their surroundings, find food sources, locate potential mates, and detect danger or threats. In essence, antennae play a crucial role in the insect's perception and interaction with their environment, enhancing their chances of survival and successful reproduction.
